CD16 expression enables antibody-mediated degranulation and thus allows T cell receptor-independent cytotoxicity. In patients with severe COVID-19, CD16-positive T cells may lead to exacerbated cytotoxicity, promote microvascular endothelial …

2020年9月2日 · CD1656 are an important NK (Natural killer) cell subset. Quick facts: – NK cells are best known for killing virally infected cells, and detecting and controlling early signs of cancer. As well as protecting against disease, specialized NK cells are also found in the placenta and may play an important role in pregnancy.

CD16 is the low-affinity IgG Fc receptor (FcγRIII-A) expressed on NK cells. Its crosslinking activates the PI3K pathway and induce the release of cytotoxic granules leading to antibody dependent cell cytotoxicity (ADCC).

2013年5月2日 · Inhibition of ADAM17 enhances CD16 mediated NK cell function by preserving CD16 on the NK cell surface to enhance ADCC. The Fc receptor CD16 is present on essentially all CD56 dim peripheral blood natural killer (NK) cells.

We sought to identify the functional and kinetic relationship of CD16 + DC to CD16 + Mo. We demonstrate that differentiation of CD16 + DC and CD16 + Mo during activation with IFNγ in vitro and as a result of an allo-hematopoietic cell transplant (HCT) …

The current review describes these properties, including the relationship to dendritic cells, and summarizes the host of publications about CD14+ CD16+ monocytes in inflammation and infectious disease in man, all of which suggest a crucial role of …

CD16, also known as FcγRIII, is crucial in both innate and adaptive immunity. There are two isoforms: CD16A on NK cells, macrophages, and neutrophils, and CD16B mainly on neutrophils. Functions include Antibody-Dependent Cellular Cytotoxicity (ADCC), phagocytosis, and inflammation regulation.

Antibody-dependent cellular cytotoxicity (ADCC) is exerted by immune cells expressing surface Fcγ receptors (FcγRs) against cells coated with antibody, such as virus-infected or transformed cells. CD16, the FcγRIIIA, is essential for ADCC by NK cells, and is also expressed by a subset of human blood monocytes.

2013年5月2日 · The Fc receptor CD16 is present on essentially all CD56 (dim) peripheral blood natural killer (NK) cells. Upon recognition of antibody-coated cells it delivers a potent signal to NK cells, which eliminate targets through direct killing and cytokine production.

2016年12月2日 · Neutrophil specific Fcg receptor IIIb (CD16b) is a glycosylphosphatidylinositol-anchored low-affinity glycoprotein that plays a significant role in phagocytosis and the clearance of immune complexes. CD16b has numerous polymorphic variants; the most relevant variants are associated with human neutrophil antigens (HNA) -1a, -1b, and -1c.

CD16 is an antigen that acts as the low-affinity Fc receptor for complexed IgG-FcγRIII. It is predominantly expressed on NK cells and macrophages and acts as an activating receptor for the IgG Fc domain.

CD16 is a low affinity IgG receptor found on various immune cells such as natural killer cells and T-cells. It plays a role in antibody-dependent cell-mediated cytotoxicity and is also expressed on granulocytes, macrophages, and other immune cells.

CD16a is a receptor for the Fc portion of IgGs and is responsible to trigger NK cell-mediated ADCC. The knowledge of the mechanism of action of CD16a gave rise to several strategies to improve ADCC, by working on either the mAbs or the NK cell.

CD16 is expressed on macrophages, natural killer (NK) cells and neutrophils. Their expression is constitutive, although cytokines and lymphokines can modulate their expression levels.

2016年2月15日 · Our findings support an important role of CD16 + monocytes in the steady-state immune surveillance of the CNS and suggest that CD16 + monocytes shift to sites of inflammation and contribute to the breakdown of the blood–brain barrier in CNS autoimmune diseases.

Unlike circulating classic CD14 hi CD16 − subpopulation, the CD16 + monocyte subset was expanded in ITP patients with low platelet counts on thrombopoietic agents and positively correlated with T-cell CD4 + IFN-γ + levels, but negatively with circulating CD4 + CD25 hi Foxp3 + and IL-17 + Th cells.

2016年9月27日 · Antibody-dependent cellular cytotoxicity (ADCC) is exerted by immune cells expressing surface Fcγ receptors (FcγRs) against cells coated with antibody, such as virus-infected or transformed cells....

The marker "CD16+ or CD56+/ CD3+" refers to a subset of immune cells that express CD16 or CD56 surface proteins along with CD3. These markers are typically associated with a specific type of T cell known as NKT (Natural Killer T) cells.

21 小时之前 · America's ice-climbing epicenter was facing a bleak future, with climate change endangering its water supply, until an unlikely savior came to its rescue: a nearby silver mine.

CD163 is a high affinity scavenger receptor expressed primarily on the surfaces of monocytes and macrophages [1]. Due to its specificity for the alternative M2 macrophages, it is regarded as a marker for M2 macrophages activation in response to inflammatory stimulation.
